Strategy's Capital Structure: From Senior Debt to Common Stock — and Where STRC Fits

Strategy — the company behind STRC — has one of the most complex capital structures of any publicly traded company. It operates not just as a software business but as a leveraged Bitcoin acquisition engine, and it has built a multi-layered financing stack to fund that strategy. Understanding where STRC sits within that stack helps clarify both the instrument's risk profile and why its yield is set at the level it is.

What is a capital structure?

Every company that raises money creates a hierarchy of claims on its assets and income. At the top sit creditors — who have legally enforceable claims and must be paid first. At the bottom sit common stockholders — who absorb losses first and are paid last. In between, depending on how a company has financed itself, there may be multiple layers of debt and equity at different levels of priority.

This ordering matters enormously in stress scenarios. If a company encounters financial difficulty, assets are distributed from the top of the stack downward. Those at the bottom receive what is left, if anything. Understanding where an investment sits in this hierarchy is fundamental to assessing its risk.

Layer 1 — The debt: convertible senior notes

At the top of Strategy's capital stack sits its debt. As of May 2026, Strategy carries approximately $6.7 billion in convertible senior notes — bonds issued to institutional investors across multiple tranches and maturities. Several tranches carry 0% interest, with investor returns coming instead from a conversion feature: the right to convert the bond into MSTR common stock at a pre-set price.

These notes sit at the very top of the distribution order. Interest payments are processed before any dividend is paid to preferred or common stockholders. In a liquidation scenario, bondholders would have first claim on Strategy's assets — including its 843,000+ Bitcoin — ahead of every equity holder in the stack.

The low-interest convertible structure is deliberate. Strategy raises cheap capital to accumulate Bitcoin, betting that Bitcoin's appreciation will more than offset any dilution from eventual bond conversions. This high-conviction approach shapes everything below it in the stack.

Layer 2 — The preferred equity tier: five series

Below the convertible notes, and above MSTR common stock, sits Strategy's preferred equity tier. As of 2026 Strategy has issued five separate preferred stock series totalling approximately $15.5 billion in notional value. Each pays dividends and each ranks ahead of common stockholders in both dividend priority and liquidation preference — but they are not all equal to one another. Within the preferred tier, seniority varies from series to series.

STRF — most senior preferred (10% fixed, quarterly)
STRF sits at the very top of the preferred hierarchy, making it the most protected of the five series. It pays a fixed 10% annual dividend in quarterly cash payments of $2.50 per share. As the most senior preferred, STRF holders have priority over all other preferred stockholders if Strategy were to reduce or suspend dividends, and they rank ahead of the other four series in a liquidation.

STRC — second most senior preferred (currently 11.50%, monthly)
STRC is the preferred stock tracked on this site and the second most senior in Strategy's preferred hierarchy — only STRF ranks above it. It launched in July 2025 at a 9% annual dividend rate and has stepped up monthly since, reaching 11.50% — equivalent to $0.958 per share each month. Its rate adjusts monthly to keep its market price close to its $100 par value: if the price drifts below par, the rate rises to attract buyers; if it drifts above, the rate falls. Dividends are paid monthly in cash, with no conversion feature and no fixed maturity date. Its position as the second most senior preferred, combined with monthly income and an adjustable rate mechanism, has made STRC the dominant instrument in Strategy's preferred lineup.

STRE — euro-denominated preferred (10% fixed, quarterly)
STRE is Strategy's only non-dollar preferred stock — it is denominated in euros, with a stated value of €100 per share. It was designed specifically to access European capital markets, listing on the Euro MTF market of the Luxembourg Stock Exchange rather than Nasdaq. Its 10% annual dividend is paid quarterly in euros, and the offering raised €620 million — upsized from an initial target of €350 million due to strong institutional demand. STRE is available only to professional and institutional investors within the European Economic Area; it is not available to retail investors in the Euro area or the UK. Within the capital stack, STRE sits below STRC but above STRK and STRD.

STRK — convertible preferred
STRK is the only convertible preferred in Strategy's lineup, sitting below STRE in the hierarchy. Each STRK share can be converted into 0.1 shares of MSTR common stock, giving holders some upside participation in Strategy's Bitcoin-driven equity performance alongside the income stream. This conversion feature makes STRK different in character from the other series — it blends fixed income with equity optionality, at the cost of sitting lower in the preferred stack.

STRD — most junior preferred (8% stated rate)
STRD sits at the bottom of the preferred tier, just above MSTR common stock. It carries an 8% stated dividend rate — the lowest of the five series — which reflects its position as the most junior preferred. Because it is last to receive distributions within the preferred tier, investors require additional yield compensation. STRD often trades below its $100 par value, pushing its effective yield well above its stated 8% rate.

Layer 3 — MSTR common stock: the bottom

At the very bottom of Strategy's capital structure sits MSTR — the common stock. Common stockholders absorb losses first and are paid last. They have no priority claim on dividends or assets; if Strategy faces financial difficulty, common holders receive only what remains after every creditor and every preferred stockholder has been satisfied.

What common stockholders do have is uncapped upside. If Strategy's Bitcoin holdings appreciate dramatically and all senior obligations are met, the residual value flows to MSTR holders. This is the fundamental tradeoff in capital structure design: MSTR carries the most risk and the most potential reward; STRC investors sit well above common equity — with a contractual income stream and a stable $100 par reference — but give up that open-ended upside in exchange.

The full picture: Strategy's stack at a glance

From top to bottom, Strategy's capital structure looks like this:

1. Convertible Senior Notes — ~$6.7B in debt; paid first in all scenarios
2. STRF — most senior preferred; 10% fixed rate; quarterly USD payments
3. STRC — second most senior preferred; 11.50% adjustable rate; monthly USD payments
4. STRE — euro-denominated preferred; 10% fixed rate; quarterly EUR payments; EEA professional investors only
5. STRK — convertible preferred; equity upside via MSTR conversion
6. STRD — most junior preferred; 8% stated rate; just above common equity
7. MSTR common stock — absorbs losses first; uncapped upside

Why STRC has become the dominant preferred series

Of the five preferred series in Strategy's lineup, STRC has grown into the standout instrument by almost every measure. As of mid-2026 it has scaled to a $6.4 billion market cap, with Strategy raising $5.6 billion in STRC proceeds in the first half of 2026 alone. Daily trading volume regularly exceeds $375 million — making it one of the most liquid preferred equity instruments in the US market — while its 30-day historical volatility has fallen to just 1.7%, unusually low for any instrument with Bitcoin exposure.

Several structural features explain why STRC has attracted this level of capital and attention:

• High seniority with a premium yield — STRC is the second most senior preferred in the stack, ranked immediately below STRF, yet it yields significantly more. Investors get near-top-tier protection with a rate that has climbed to 11.50%, outpacing every other series on a current income basis.
• Monthly payments — All other Strategy preferred series pay quarterly. STRC pays every month, which is attractive to income investors who want regular, predictable cash flow rather than waiting 90 days between distributions.
• Adjustable rate mechanism — The monthly rate reset is designed to keep STRC trading near its $100 par value. This built-in stability mechanism has succeeded in keeping price volatility unusually low and makes STRC behave more like a cash instrument than a typical preferred stock.
• $2.25 billion USD reserve — Strategy has set aside $2.25 billion in cash reserves specifically to cover dividend and interest obligations, providing approximately 2.5 years of coverage. STRC investors have a concrete, quantified liquidity buffer standing between them and any dividend disruption.
• $413 million distributed to date — As cumulative distributions have grown, STRC has demonstrated a consistent payment track record since its July 2025 launch, building investor confidence in its income reliability.

The result is that STRC has established itself not just as the largest of Strategy's preferred series, but as the benchmark for the emerging digital credit asset class. Its combination of structural seniority, monthly income, price stability, and deep liquidity has made it the preferred choice for institutional and retail income investors seeking Bitcoin-adjacent yield.

What this means for STRC investors

STRC's position in the stack has direct implications for how to think about the investment:

• Second most senior preferred — Only STRF ranks above STRC within the preferred tier. Four of the five series — including the convertible STRK and the most junior STRD — sit below it. This is a meaningfully protected position within what is a complex and well-capitalised preferred structure.
• Senior to common stock — STRC dividends must be addressed before MSTR common stockholders receive anything. This provides meaningful income protection relative to holding MSTR directly.
• Junior to all debt — Strategy's $6.7 billion in convertible notes ranks ahead of STRC in every scenario. If Strategy faced severe financial stress, debt obligations would be serviced before any preferred dividend is paid.
• Bitcoin is the underlying reality — Across the entire stack, Strategy's ability to service its obligations depends on its 843,000+ Bitcoin treasury. A sustained decline in Bitcoin prices would place increasing pressure on the stack from the bottom up, beginning with MSTR common stock and working toward the preferred tier over time.

Why the yield premium makes sense

STRC's 11.50% adjustable yield is meaningfully higher than conventional preferred stock, which typically yields 5–7%. That premium exists because of the structure described above. Investors are compensated for accepting exposure to Bitcoin's price trajectory through Strategy's balance sheet, sitting below $6.7 billion of senior debt, and holding a perpetual instrument with no guaranteed return of principal. That said, within the preferred tier itself STRC occupies a strong position — second only to STRF — and its deep liquidity, monthly payments, and $2.25 billion reserve buffer make it the most developed and investor-friendly of the five series. The yield is not a sign of distress; it reflects a deliberate and transparent risk profile that differs from conventional preferred equity. Understanding the capital stack is the foundation for deciding whether that tradeoff suits your income objectives.
